Technical description

In the Linux kernel, the following vulnerability has been resolved:

io_uring: fix multishot accept request leaks

Having REQ_F_POLLED set doesn't guarantee that the request is

executed as a multishot from the polling path. Fortunately for us, if

the code thinks it's multishot issue when it's not, it can only ask to

skip completion so leaking the request. Use issue_flags to mark

multipoll issues.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
